Representative staining patterns with MAbs to PGL-I, LAM, 65 kd, and 36
kd in the lesional skin of untreated MB and PB patients.
Immunoperoxidase staining of sequential sections of a MB
lesion (BI 4+; A to
D) and of a PB lesion
(BI 0; E to
H) with MAbs against PGL-I
(A and E), LAM
(B and F), 65 kd
(C to G), and 36 kd
(D to H). All sections were
counterstained with hematoxylin. Immunoperoxidase single staining;
magnification, ×125. Note the dark staining in the basal layer is due
to melanin-containing melanocytes and not due to immunostaining.
